PERCY W. ELLIS, OF DENVER, COLORADO.

CAR-SEAL.

v To all whom 'it may concern.'

Be it known that I, PERCY W. ELLIS, a citi- Zen of the United States,residing in the city and county ol' Denver and State oi' Colorado, haveinvented certain new and use'l'ul 1mprovements in Car-Seals; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the figures of reference marked thereon,which form a part ol' this specication.

My invention relates to improvements in car seals, my object being toprovide a device of this class which shall be simple in construction,economical in cost, reliable, durable and efficient in use, and to thisend the invention consists oi' the features hereinafter described andclaimed, all of which will be fully .understood by reference to theaccompanying drawing in which is illustrated an y embodiment thereof.

In this drawing, Figure 1 is a perspective view of my improved car sealshown in the unlocked position. Fig. 2 is a top plan view showing thecasing in horizontal section, the parts being in the unlocked position.Fig. 3 is a similar view showing the parts in their locked position.Fig. 4 is a vertical longitudinal section taken through the deviceshowing the same in the unlocked position. Fig. 5 isa similar viewshowing the parts in the locked position. Fig. 6 is an underneath vviewof the device, shown in the locked position. "Fig, 7 is a top view ol'the same.

Fie' c s u n a b 8 is a iragmentary sectional view similar to Fig. 4 butshowing the parts on a larger scale. -Fig. 9 is a similar view showingthe parts in the locked position. Fig. 10 is a perspective view indetail ol' the locking dog. Fig. 11 is an extended view ol' the flexiblestrip or sealing strip shown in detail.

Thc'same reference characters indicate the same parts in all the views.

Let the numeral 5 designate a casing in which the sealing strip isanchored said strip being bent at 6 and provided with upper and lowermembers 7 and 8 located within the casing'. This casing is bent belowthe member 8 and secured thereto in any suitable manner (see Fig. 6).The two members l7 and v8 are separated, the member 8 being providedAwith a slot 9 in its front portion and an oy ening 10 in its rearportion.

ing a downwardly projecting tooth 16 located at its rear extremity. Thepart 15 is connected to the plate 13 by an upwardly projecting part 17.When the parts are assembled, the plate 13 of the dog rests upon themember 8 olI the sealing strip within the casing, while the part 15occupies a position above the member 7, the upwardly projecting part 17occupying a position within the slot. It will be observed that the part13 is below the member 7 ol`- the sealing strip while the part 15 isabove said member when the parts are in the assembled position andbefore the locking operation.

As shown in the drawing the bottom of the casing is flat while its topis provided with a channel which is downwardly inclined from thei'orward to the rear portion 0i' the casing. When the parts are in theunlocked position, the member 15 o1' the dog, protrudes into thischannel and engages the top thereof at a point 'forward of the opening10. The forward extremity oi' the casing is provided with a slot 20adapted to receive the free extremity 21 o1" the sealing strip, the samebeing provided with an aperture 22.

Assuming that the parts are assembled as shown in Figs. 2, 4 and 8 oilthe drawing, il' it is desired to lock the seal, the free extremity 21is inserted in the slot 20 o'l' the casing and the l'ree extremity movedrearwardly. This i'ree end o'll the strip iirst comes in contact withthe upwardly projecting part or ol'lset 17 oll the member 15, and as thesaid end is moved rearwardly, the dog is carried -in the sainedirection, its rear extremity being forced downwardly by the downwardinclination of the top of the casing above the channel 18. During thisrearward movemont of the dog, the member 7 of the sealing strip is bentdownwardly until tho tooth 16 ol' the dog reaches the opening 1() whichit enters and moves downwardly giving a tilting movement to the dogwhereby the forward extremity ol' the part 15 is caused to engage the towall ol` the casing above the channel 18, wiliile the 'forward extremityof the dog moves upwardly, causing the tooth 14, to enter the aperture22 in the free extremity o'll the sealing strip, and also the slot 9 inthe forward portion ol the yielding support 7 since the forwardextremity of this in o0 12Lwhich is also located within the l su ort isalso in osition to receive the said g e PP P tooth thus producing adouble locking effect since the removal of the free extremity of thesealing strip from the casing is resisted by the engagement of bothteeth of the dog or locking device with the yielding support.Simultaneously with this movement of the locking dog, the rear ortion ofthe member 7 of the Strip Within the casing springs upwardly wherebythis member cooperates with the rearward tooth 16 of the dog to bringabout the locking result. It will thus be observed that the freeextremity 20 of the sealing strip is. securely locked in place withinthe ,casing and cannot be removed without mutilating the device andleaving evidence that the seal has been tampered with.

Having thus described my invention, what I .claim is:
